[Trigger] Seems like I need help

[Fimbus]

I'm currently working on a map, and I'd like the main hero to have an aura that increases the attack damage of affected unit (that's no problem to make).
Furthermore I want units under the effect of the aura to, when killing an enemy unit to increase the attack speed of each allied unit in 600 of the unit.
I thought this would be quite easy, but as I need to work unit groups (which I've never really done before) one thing bugs me.
How can I create a dummy at each individual unit, and then make the dummy cast a attack speed-increasing spell at each unit? - Or is there a easier/more efficient way to do this?

If you change it to: "Increase attack damage" you could skip the whole group thingy and dummy-cast roar. For attack speed try using a dummy with an aura that has duration.

Or Create one dummy (invis to everyone. Most likelly without any model) that will only have a Atack speed aura which for every kill nearby, is created with the level 1 of the ability and increases for every kill

What if a unit gets 10 kills? An ability with 10 levels increases load time big time.

However, there is no way to add multiple attack speed buffs, so levels seem to be your only option. But, to reduce lag, use many abilities with different bonuses.
